Pharmaceutical firm AstraZeneca is confident it will reach a deal with unions to end renewed strike action over changes to the company's pension scheme.
The Local Government Pension Scheme will become "unsustainable" following cuts outlined in last month's Comprehensive Spending Review, the GMB warns.
Public sector workers will budge no further on pension reforms and will fight recommendations in Lord Hutton's review, unions say.
Strike action over changes to pension arrangements at AstraZeneca have entered their third week.
Concerns over a potential attack on workers' pensions at the Teeside Cast Products manufacturing plant are "very, very premature", a regional union representative says.
